摘要:
A furrow closing wheel for closing an open furrow. The furrow closing wheel has a pair of rims mounted for rotation about a generally horizontal axis of rotation. The pair of rims are mounted at an angle with respect to one another with the rims being spaced apart. The distance between the rims decreases as the rims rotate from the top of the direction of rotation to the bottom of the direction of rotation and increases as the rims rotate from the bottom of the direction of rotation to the top of the direction of rotation. Spikes protrudes radially outwardly from the rims. Teeth extend inwardly and laterally from rims. The spikes are adapted to penetrate the sides of a furrow to crumble the furrow walls and push soil in the direction of the furrow opening and the teeth mesh to press down on the furrow to properly close the furrow.
